I see the problem, you have more power modes than space allocated to hold them.
 This patch should fix the issue:

diff --git a/drivers/gpu/drm/radeon/radeon.h b/drivers/gpu/drm/radeon/radeon.h

        /* XXX: use a define for num power modes */

        int                     current_power_state_index;


I'll write up a better one to dynamically allocate space depending on the
number of tables.
